COBRUGATED STRUCTURE FOR RAILWAY CARS. i

Application Med lay 16, 1825. Serial No. 30,778.

My invention relates to the construction of railwaycars having parts formed of metallic plates which are subjected to lateral, buckling and sometimes torsional stresses. Said parts are made of one or more metallic lates or panels formed with vertical or horizontal corrugations or other integral stiieningor bracing means to resist such stresses. l/Vhile eii'orts are made to block the lading in the car, the shocks caused by the heavy locomotives, the emergency air brake and the classification hump tear the lading away from its moorings and throw it against the end of the car, the lateral weav- .ing of the car throws it against the side of the car, and the impact throws it against the bottom of the car. My invention is adaptable to several parts of a railway car, such as side doors, side walls, floor sheets (sloping or otherwise)7 hopper doors, roo sheets, etc., but it is especially adaptable for use as the end wall of a railway car and is also adapt-able to boX, gondola or other types of cars.

One of the objects of the invention is to provide metallic parts of a railway car, which have great strength to resist the torsional and weaving stresses which exist in a railway car when moving in service.

These stresses arecaused by the inertia ofthe roof and superstructure when the train is suddenly stopped; rough or uneven track; the superelevation of the track on curves;

' the lateral inertia in rounding curves; eccen- `tric thrust due to the lading bein secured to one sideiorn the car; the cars eing cornered; the use of push pole pockets, etc. Suchstresses rack and distort the superstructure which ydecreases the life of the car, and also causes the canto leak grain, sand and other such material. Furthermore, such stresses cause leaky roofs and leaky and inoperative side and end doors.

The tendency of an all metal end wall to bulge is resisted partially by the corrugations, stitfening members or whatever `means have been provided to transmit such stresses to the side wall or frame members of the car. Such tendency is also resisted by the corner post of the car acting as a vertical beam supported at its top and bot-tom and sustaining a horizontal load; in other words, the bulging of the end would pull the o posite corner posts toward each other. T is bulging also tends to4 pull the end (or side) Y late downwardly and the end (or side) sil upwardly. Another object of the invention is to reinforce the frame members against thrust perpendicular to their length by means forming a part of a corrugated or otherwise reinforced metallic end wall.

Since the corrugated metallic wall is braced against buckling it in itself has considerable resistance to the lateral stresses but the wall must be well secured tothe frame members, (post, sill and plate) in order to secure the co-operation between these frame members and between the metallic wall and the frame members. Another object of the invention is to obtain an limproved method of securing a corrugated metallic wall to the frame members of the car.

part of the metallic late is pressed to form a panel 14 surroun ed by an integral part of the plate positioned angularly to the plane of the panel. If this surrounding part constitutes the edges of the plate then 1t would technically be called a flange. I-Iowever, it may be provided with a laterally extending part (or flange 28--27) so that'the surrounding part would then technically be called a Web. This laterallyextending part is not an element of the broader claims of this application, therefore, to avoid the use of two different words to designate the saine-element, in different claims, the Word web is used to designate that part of the plate surrounding the panel and positioned at an angle thereto whether it constitutes the edges of the plate or not.

It has been proposed to press the central portion of a metallic plate (or plates) so as to form a continuous. web surro-unding a panel and to reinforce this panel by horizontal corrugations or other integral reinforcements which traverse the panel and terminate adjacent the opposite portions of the web. In such an arrangement the load upon the horizontal corrugations is transmitted to the continuous web only through the intermediate mcans of the fiat portion of the plate lying between the end of the horizontal corrugations and continuous web. It has also been proposed to press the central portion of a metallic plate (or plates) so as to form a web (supposedly) surrounding a panel and to reinforce this panel by horizontal corrugations or other integral reinforcements which are the saine depth as the web Where they merge into it. In such an ar-v rangement the web as a beam is destroyed.

In my construction the transverse oorrugations destroy only a part of the value of the web, leaving a remaining portion which eX-, tends continuously around the panel to receive the stresses from the horizontal corrugations and to function as a beam and a stif,

fener. Such stresses are transmitted directly to the remaining portion of the web.

That portion of the web between the corrugaticns serves as an excellent place for an attaching bolt or rivet because a bolt or rivet so positioned then also restrains the corrugations against deiiection. Furthermore, a bolt or rivet so positioned prevents the web from buckling as it has a tendency to do when acting as a beam. i

In the drawings the usual artsiof the car are shown such as the end sill 1; end platel 2; side sill 3; side plate 4; side girth 5; corner post 6; side linin 7; side sheathing 8; end ining9 and end ascia 10.

In my construction the central portion of the metallic plate 11 (or plates 11--12) is pressed to form a continuous web 1.3-16 surrounding a panel 14. vThis panel 14 is reinforced with corrugations 15 or integral A'ribs which traverse the panel (in the Aprefeparred form) and merge into a part of the op' ,ositevv portions 16 of the continuous web. Ty maining portion 26 of thecontinuous lweb three (or preferably four) sides of the wall." 'I

extends continuously and uninterruptedlyon This web receives the load from the corra-'y gations and forms a beam' or stiiener to prevent bulging in transmitting the 'load rom the corrugations to the frame ofthe car. These remaining portions of the verti- 3 cal parts 16 of the continuous web are pre` vented from buckling or deliecting by being formed integral with the horizontal parts 13 of the continuous web (preferably b radialV portions 17.) The web preferably against the adjacent frame member, such as corner post 6, end. sill 1 or end plate 2an'd is secured thereto by bolts'18 lwhich are preferably positioned between the corruga-y tions. Other means 19 are provided to secure the plateto 'the frame member which; 'f are preferably positioned in alignment with the corrugations. `These two means may be used jointly or severall The plate is secured to the end sill 1 y bolts 20--21 and to the end plate by bolts 22-23'.

The corrugations may be made the same y shallow corru ations 24 adjacent the conf tinuous web w ich merge into a lesser num-y I' ber of larger and deeper (therefore stronger) corrugations 25 adjacent the midp dle of the plate. These shallower and deeper corrugations may beso positioned and diiis mensioned that the length of the center line of thev metal of the shallower corrugations (see Fig. 8) is the same 'as the length of the center line of the metal of the deeper corru- 'gations (see Fig. 6) 'which is., a material l manufacturing advantage, as it more evenly distributes the draw and stretch of the metal due to pressing the corrugations in the plate.

, Figs. 11 to 19 inclusive show a form of the invention applied to a steel frame car wherein 40 is the end sill an le; 41 the end plateg 42 the corner ost; 43 t e side lining; 44 the A side lining nai ing strip; 45 theside 'sheathing and 46the end lining. The corner post 42 may be reinforced-by diagonal braces 47 and 48 extending back toward the middle of the car which are secured to the side plate and side sill, respectively.

.In this form the end wall comprises two (or more) plates 49-50 secured together and each individual plate has its central portion pressed to form a continuous web 51 surrounding a panel 52-and the corrugat1ons 53 are shown the same'depth as the web for the major ortion of their length but are ofA less dept than the web where they merge into it.

Figs. 20, 21 and 22 show another form of the invention wherein the central portion of an individual sheet is pressed to forma web surrounding a panel and the corrugations are of less depth than the web for their entire length.

Figs. 23 and 24 show an enlarged section of the corner post and illustrate the relation of the web 16, corrugations 24, and ati taching bolts 18 and 19.

While I have shown and described the corrugations positioned horizontally, it is understood that the corrugations may extend vertically or otherwise, and still come within the scope of the invention, and, furthermore, while I have .described and claimed the wall made of a plate, it is understood that it may be made of one or more united plates and still come within the scope of the invention.
